T'oaltwlwm t may concern;

Be-it known that I, HENRY E. HnNRicKs, a `citizen of the United States, residin at Oalrfliarkf, 'in the county of lCook and tate of Illinois, have `invented new Aand useful Improvements in ,Molding Machines, of`

which the followinglisa specification.

This'invention relates 4to apparatus. for deliver-ing sand to mold flasks, and its object is to ,provideanovel and improved appa-` in order that the same may lbe better understood, reference is had tothe accompanying drawings forming a part of this speci-fication.V

"In the drawings,

Figure 1 is an elevation partly in section i of a portion ofthe apparatus, and

Fig. 2 is a similar view of a continuation thereof. y

',Rcferring specically to the drawings, 5 denotes a hopper which is positioned beneath thelower or discharge end ofA an inclined table 6, -which'la'tter, in turn, has Vits upper or receiving end positioned beneath the lower or discharge Vend of a second inclined table 7. At '8 is shown an endlessconveyer which delivers sand "to the table l7 from which latter it slides onto the table 6, and drops fromgthe latter into the hopper 5. The conveyerS ris charged from a suitable Asand rese`rvoir.`` Thebottor'n of the hopper 5 has a depending outlet spout 9 beneath which is located ailask' 10to be charged. n

At 11 is shown 'a suitable 'stand having-a heavy's'quared top12from which rises a `crown 13 reinforced byradial webs 14. The crown 13 is hollow to seat and hold'the lower end of a hollow post rising to a suitable height to Vservea's asupport Vfor the apparatus. The top ofthe post 15 is fitted with a head 16 projecting laterally therefrom a 'suilicientdistance-to pivotally sup- 1920. Serial No. 394,921.

port a pair of upstalnding parallel link bars 17 supporting the table 7.

On post 15 is also rigidly clamped alheavy two-part sleeve 18 vsupporting a horizontally projecting arm 19 fitted at its outerend with a head 2O having a socket 21 `to seat 1the spherical upper 1end 22 of a ystem 23 which depends from the head l and supports a beam 24, the latter being swiveled to the lower end of the stem. One end of the beam 21lis `counterfweighted, as shown at 25, and its opposite end carries an angle bar 26Jto" which are pivo'ted parallel link bars 27 supporting the table 6.

On the outer 'end-of the beam 24 is a head 28 having a socket 29 to seat the spherical upper end of la stem 30 supporting the hopper 5, which latter is therefore swiveled so that it maybe rotated and also swung in any direction to directthesand to any portion of the liask 10. As the beam 24 from which the hopper 5 is hung is iswiveled and counterweighted, itcan-be easily tilted Ito elevate or lower the hopper, and also swung horizontally to swing thehopper bodily.

In the hopper spout 9 is mounted fan endless conveyer 31 for carrying the sand down the same and forcibly discharging it into the 4flask 10. The conveyer 31 is Idriven -at a high rate of speed, with the resultth-at the sand is thrown into the flask 10 Vwith such force that it is properly rammed or 4cornpacted therein without further compression, and it is not necessary to resort to lthe use of a ramming or tamping tool.

The conveyer 31 is, of course, vertically positioned, its upper end extending far enough into the hopper 5 to gather the sand therein, and its lower endbeing positioned at the bottom or discharge` end of the spout 9.

The conveyer 31 is driven by an electric motor 32 vmounted on the counterweighted end`25 of the beam 24 so that italso acts as a counterweight. A belt drive 33 is provided between the'motor shaft andthe upper conveyer shaft 34. i

The blades of the conveyer 31 are curved to gather the sand from the hopper 5 and throw it downwardly rather than laterally at the bottom of the s out 9.

The tables 6 and are adapted to be shaken or agitated "to break up all lumps in Cil the sand, the following means being provided for this purpose In the post 15 is housed a vertical shaft 35 projecting from the top of the post and having here a gear 36 and a crank disk 37, the latter being connected to the table 7 by a pitman 38. The gear 36 is in mesh with a gear 39 on a vertical countershaft 40 located outside the post 15 and having a pulley 41 which is connected by a belt 42 to a pulley 43 on a shaft 44 supported in a bearing on the head 20. The shaft 44 drives an eccentric 45 having its rod 46 connected to table 6. It will therefore be seen that the tables 6 and '7 are given a vibratory motion when the 4a horizontal shaft 49 having a driving connection, through a bevel gearing 50, with the shaft 35.

The shaft of the motor 47 is also geared to a pulley shaft lbelted, as shown at 52,

to the conveyer 8 for driving the same.

The head 16 has a bearing 53 supporting the upper end of the shaft 40, the lower end of said shaft being supported by a bearing 54 on the crown 13 of the stand 11.

The shaft 35 has a ball step bearing on the top 12 of the stand 11.

yThe clamp 18 is adjustable up or down on the post 15 to locate the hopper 5 and the parts ,associated therewith the proper dis- "tance above the flasks 10. When this adjustment is made, the pulley 41 must first be released from theshaft 40`so that it may be slid up or down thereon to follow the clamp 18, and after the desired adjustment` `'is effected, the pulley can be again made fast associated with the hopper for forcibly ejecting the contents thereof, asecond shaking table carried by the support and discharging on the hist-mentioned table, a drive shaftlon the support, a counter-shaft on the support obtaining motion from the drive shaft, driving means for the first-mentioned table carried by the aforesaid arm, a driving connection between said means and the countershaft, and a driving connection between the A'drive shaft and the rst mentioned table.

and a driving connection between the counter shaft and the second mentioned table.`
